The U Gem is located at R.A. = 07h55m05.2s, Decl. = 22° 00' 04 " (equinox 2000.0), V-band range 8.8 - 15.3 mag (more detail for U Gem). We observed the star on seven nights, beginning on Nov. 6, until Dec. 21, 2007. The data was collected by using the automated 25-cm f/4.2 Schmidt-Cassegrain with a CCD camera cooled to -22 °C and single Johnson V band. The exposure time was 80 seconds for first night and 120 seconds for other six nights. All images were bias, dark and flat subtracted. Altogether we collected 1140 data points. All data was sent to AAVSO.
